Does this page explicitly cover ac drive sto intent?

Yes. ac drive sto is handled as an alias intent on this canonical URL without creating a separate competing route.

Is safe torque off the same as emergency stop for every machine?

No. STO removes torque-producing power, but residual motion and stopping strategy must still be validated against machine-specific hazards.

Does STO activation prove the motor side is electrically safe to work on?

No. STO is not electrical isolation. Follow lockout and voltage verification procedures before electrical work.

When should I prefer SS1 plus STO over STO only?

When uncontrolled coasting can create unacceptable risk, especially with high inertia or vertical-axis scenarios.

Can this page output replace legal conformity documentation?

No. The tool output is engineering triage guidance and does not replace full conformity assessment or legal interpretation.

What should I do after a high-risk result?

Freeze release assumptions for that axis, escalate to architecture review, then rerun validation after mitigations are implemented.

Can I share a direct alias link with operations teams?

Yes. Share /safety/sto-sls#ac-drive-sto-alias to open the canonical alias section directly.
